ABSTRACT
Important catalyst properties such as gasoline and coke selectivity are listed in Table 6.1 [2]. A catalyst change could be made to improve fluid catalytic cracking (FCC) unit operation for any of the benefits listed in the table. When a change is being sought, however, the trick is to not have another aspect of the FCC operation deteriorate such that the benefit sought is nullified by other changes. All of the catalyst suppliers have a line of products that will enhance each of the benefits shown in the table [3].
